metafun: formatting numbers

[Peter Münster]

Hello,

Formatting numbers seems to be buggy:

\starttext
\startMPcode
drawoptions(withpen pencircle scaled .25pt withcolor .5white) ;
draw hlingrid (0, 20, 1, 20cm, 10cm) ;
fmt_pictures := false ; % use TeX as formatting engine
draw hlintext.lft(0, 20, 1, 20cm, "@3e") ;
\stopMPcode
\stoptext

See also page 381 of latest metafun-s.pdf.

in mp-grid you can change:


def do_initialize_numbers =
   if not numbers_initialized :
     init_numbers ( textext.raw("$-$")          ,
                    textext.raw("$1$")          ,
                    textext.raw("${\times}10$") ,
                    textext.raw("${}^-$")       ,
                    textext.raw("${}^2$")       ) ;
     if unknown _trial_run_ :
       numbers_initialized := true ;
     else :
       % no reset, otherwise textexts get out of sync
       % slows down graphics a bit but not much
     fi ;
   fi ;
enddef ;
